Specification forming part of Letters Patent No. 193,950, dated August7, 1877 application filed May 5, 1877.

To all whom it may concern Be it known that 1, WILLIAM HEATH, of Bath,in the county of Sagadaho'c and State of Maine, have invented certainnew and useful Improvementsin Snap-Hooks and I do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

The nature of my invention consists in the construction and arrangementof a snap-hook, as will behereinafter more fully set forth.

In order to enable others skil'ed in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichthe figure is a perspective view of my improved snaphook.

A represents the hook with shank B, at the end of which is formed aloop, G. In the front of the shank B, at its junction with the loop 0,is formed a groove, in which are placed two springs, D D, which arefirmly riveted to the shank.

The end of the spring D very nearly meets the point of the hook A, justso close that it will go clear and work by the same both in and out.

In the snap-hooks now generally in use the ill spring runs by the pointof the hook and underneath, so that it cannot be worked but one way, andthen it has to be pressed down with the thumb or finger in order to getit unhooked. By my invention of having theend of the straight flatspring D coming nearly to the end of the hook, this difticulty isobviated and the spring will work both ways.

The outer spring D is shorter, and is simply applied to give additionalstrength to the mainspring D,

This snap-hook is mainly intended for drivingreins, but may also be usedon other parts of the harness. It can be attached and detached veryeasily, and'is perfectly reliable.

Having thus fully described my invention,

what I, claim as new, and desire to' secure by
